输电线路导线覆冰严重威胁电力系统的安全运行,对型线和普通绞线覆冰过程及其特性开展深入研究可为电网输电线路防覆冰技术和瓦型导线的推广应用提供参考。在人工气候室内模拟自然覆冰条件,对LGJ-185/10、LGJ-400/65型普通绞线和JNRLH60X/LBIA-185/30、Drake 1020型瓦型导线进行了试验研究,分析了2类导线覆冰异同。结果表明：在相同覆冰条件下,瓦型导线的覆冰厚度比相同直径的普通绞线大,冰棱长度则反之;直径较小的导线覆冰厚度要比直径较大的同种导线覆冰厚度增长更快,而冰棱增长则相对较慢;其他覆冰条件相同时温度越低或者风速越大,瓦型导线和普通绞线的覆冰厚度差异越明显。

Transmission line icing is a serious threat to the safe operation of power systems. Therefore, comparative study on icing performance of T-type wire and ordinary stranded wire can provide a reference for power transmission line anti-icing technology and the application of T-type wire. We experimentally investigated four kinds of conductor, namely, LGJ-185/10, LGJ-400/65, JNRI.H60X/LBIA-185/30 and Drake 1020 in the artificial climate chamber. According to the test results, we find that, under the same environmental parameters, the ice thickness of T-type wire is higher than that of the same diameter ordinary stranded wire, but the situation of icicle length is opposite. As for the same kind of wire, the shorter wire diameter is, the faster the ice thickness grows, whereas, the situation of icicle length is the opposite. Under the same icing conditions, the lower the temperature or wind speed is, the more obvious differences of ice thickness between T-type wire and ordinary stranded wire are.
